severe cold and no one seems to agree!

I am sneezing every 10 min, nose is stuffed and I'm just looking for some relief. 
I picked out a medicine that had ingredients that were on my list of approved medicines by my doctor but the pharmacist said there are things in it that isn't safe. 
What can I take?! No one seems to have the same answer so I'm stuck taking nothing
